Icon Audio or PrimaLuna?

I have a PrimaLuna DiaLogue Premier HP amp and couldn't be happier with it, driving either Focal Utopia Diablo III's or Joseph Audio Pulsars.  It has fantastic soundstage and imaging, and is probably the most hassle-free way to own a tube amp, with auto-biasing, tube failure indicator lights, and a host of other great features such as point to point wiring.  Hits way above its price point and if you really want to go nuts, buy two and switch to mono and get 140 watts per channel!

For my two cents, you cannot go wrong with the Prima Luna Dialogue Premiums. I have both the Pre-amp and two HPs as mono blocks. I'm a big fan. I have tried a few others, that shall remain unnamed, and none sound as good as what I am listening to now. You can spend a lot more and not get as satisfying results; if you spend less you will not get the build quality and high end components. Jus' sayin'.

The Prima Luna’s are fine products and have heard, along with auditioned them several times. I do own a set of Icon Audio MB90 MkII KT150 MonoBlock Power Amps and without a doubt they are excellent performers and exceed the Prima Luna’s from my standpoint. I also have an Icon Audio PS3 Mk2 MM/MC Phono Preamp that adds value to vinyl listening which off the charts. With the Icon Audio components paired up with some Acoustic Zen speakers (have both Cresendo’s and Adagio’s) sounds superb. My recommendation would be to go with the Icon Audio’s and don’t look back!
The Icon Audio group in the UK are great to corrispond and work with. They have been very helpful timely in answering questions and helping out. The guy's at Music Direct (the US distributors) are tremendous in their support too.

We have found that the Icon Audio Integrated tube amplifiers consistently out perform the PrimaLuna. In addition the Icon Audio phono pre-amplifiers are among the best available.

Icon amps are very highly thought off in the UK, they get top marks every time they are reviewed in the British audio press.
Very nice people to to correspond with also, will answer any question, no matter how banal.
